How to measure for a fireplace grate?

You will first need to gather the following items: a tape measure, a pen or pencil, and a writing pad.

Remove any items inside or in front of the fireplace that may potentially hinder you from accurately measuring. Then use the tape measure to measure the front width of your fireplace. Then get the measurement from the back width, followed by height and depth. 

width of the opening?
width in back?
height of the opening?
depth at bottom?
depth at top?

You then select an item that is smaller than and fits within all these measurements.

After measuring your fireplace, if you still have questions, email us or complete our online contact form.

Why is total energy measured in KWH kilo watt hours?

These days most formulas and tests instruments measure total energy over time in KWH allowing for easy comparison between different sources and forms of energy with an unified apples to apples comparison. For example every KG (2.2 pounds) of biomass has approximately 4.8 KWH of available energy, a 1500 watt plug in heater running for 10 hours a day will use 15 kwh of electricity which is about the same as the energy content of 1.5 liters of heating oil or 3 kg of wood. 

Kilowatt-hours are often used in typical energy calculations used by domestic users. One kilowatt-hour is equal to the amount of energy used in one hour by appliances that are rated at one kilowatt. kilowatt-hours are used because they are familiar units that are convenient to use in a domestic setting and are easily understood and converted from one form to another.

A BTU, or British Thermal Unit, is the a outdated unit of energy used to measure heat. Each KWH is the same as 3412,14 BTU hours of quantifiable measurable energy.

The average heat demand of an average-sized USA home is a under 30 KWH per day. At Hasty Heat, all of our appliances and heat exchangers are designed with the greatest surface area possible to capture and move the highest percentage of the KWH stored in your fuel into your home.

How do I clean a fireplace grate?

The best method of cleaning a wood burning appliance is with an ash vacuum since it will suck up and trap nearly all the dust generated during the cleaning process. The ash vacuums we sell in our store are best for cleaning between the tubes of our fireplace grate heat exchangers. 

A ash shovel and brush work effectively as well.

If you purchased the removable ashtray add-on, you can simply pull from under the grate and empty all the debris in a paper bag or trash bin. 

The best time to clean ash is the next day after burning a fire to ensure the majority of the hot coals are extinguished. 

Always place ashes into a metal container with a lid and let them rest for several days to prevent starting a fire when you fertilize your garden, lawn, yard, or otherwise dispose of them.

How often should I clean my fireplace grate?

We recommend cleaning your fireplace grate after every use, to ensure maximum airflow under your fire for the most intense complete clean combustion of your firewood fuel.

Remember white smoke is unburned fuel and approximately 70% of the biomass firewood energy is contained in those white wood gasses during thermal decomposition.

Inspect your grate every year for rust. You may consider adding a coat of heat-resistant paint for added protection.

What is your return policy?

We have a 60-days no-questions-asked return policy for fireplace grate purchases. Fill out our contact form to request return instructions.

After we receive and inspect your returned item, we will issue your refund less a 20% restocking fee and adjustments made for any missing parts or damage costs.
